There are many types of evidence such as scientific, historical and experiential. Science, like all other types of evidence, has it's strengths as well as weaknesses. Studies can be strongly or poorly designed and influenced by bias or any number of motivations. Data can be cherry-picked and study conclusions do not always match the evidence within. Here are a few questions to ask when critically assessing a study and it's findings:

A qualitative, systematic review argues the need for plant/oil-based medicines as alternatives to synthetic antibiotics, which are subject to pathogen resistance and negative side effects; and explores the effectiveness of essential oils as alternatives in the treatment of periodontal pathogens.
"The data indicate that unvaccinated children in the practice are not unhealthier than the vaccinated and indeed the overall results may indicate that the unvaccinated pediatric patients in this practice are healthier overall than the vaccinated."
"Vaccinated adolescents and adults may serve as reservoirs for silent infection and become potential transmitters to unprotected infants (3-11). The whole-cell vaccine for pertussis is protective only against clinical disease, not against infection (15-17). Therefore, even young, recently vaccinated children may serve as reservoirs and potential transmitters of infection.”
Whistleblower, Dr. William Thompson, claims that the CDC suppressed scientific evidence that the MMR vaccine increases the incidence of Autism in some populations. Download the files released by Dr. Thompson here.

Studies are cited on a range of vaccine-related topics such as injury related to aluminum in vaccines and increases in seizures, SIDS and allergies related to vaccination.
Perhaps as significant as the growing body of vaccine critical research is the general lack of evidence coming from pro-vaccine sources that vaccines are safe and effective. This is the case in glaring spite of any claims by authorities to the contrary.
